toms-ch es -of this character for use in the singeing o' stockings.

Heretof in fthe practice of the art, machifie's h'a been devised and employed wherei rt- 'f. s,"*p'artaking of the character ,of board'si 'h ve'been' utilized-as carriers for the stockings tofe singed, these forms supportin the stocking as the latter have pro-' gresse through the machines, and serving to distend the stockings to enable the singeing element, usually in the form of gas jets, to act upon the stockings. Such machines, however, are open to objection. Primarily, the boards employed as the forms each presents an unbroken or solid barrier when in the stockings; so that it is absolutely impossible for the hot gases to pass through the interstices of the fabric, or to penetrate from both sides of the latter, and this results in an imperfect singeing of the stocking. In the second place, each stocking must be manually placed upon its form, and, in the machines now commonly used, manually removed' therefrom after the singeing operation, although some -;machines have been devisedwherein it is proposed to automatically remove the singed stocking from the "forms; The employment of forms of the character mentioned imposes undue labor upon the operatives" of the machine, and multiplies the number ofsuchoperativesn Furthermore, these forms have notions noted by providingmeans for supportfixed path of travel through the machines, and are, therefore,susceptible of deviation from the path intended'to be followed by the-same.

SINGEING-MACHINE.

ing the stockings in distended form but capable of admittin the hot gases to and through the interstlces thereof, thus enabling the stockings to be singed to the required extent without, however, burning the same by the presence of the singeing flame.

The invention also aims to provide a singeing machine embodying in its construction means for automatically feeding the stockings to the forms and stripping the same therefrom, when the singeing operation has been completed, whereby manual effort for the accomplishment of these steps is entirely eliminated, and a resultant re duction in the number of operatives for the machine effected. V

The invention also contemplates the provision of a singeing machine wherein means are embodied for imparting to the respective forms a fixed orbital movement, during which movement the stockings are subjected tO'llhQ different steps incident to singeing,

and after completing the cycle of operations the forms are returned successively to the point of application of the stockings, there to 'be automatically charged with the un-- singed stock.

With these general objects in view, and others that will appear as the nature of the improvements is better understood, the invention consists substantially in the novel construction, combination and arrangement of part-s hereinafter fully described, illustrated in the accompanying drawings, and pointed outin the appended claims.

While the form of the invention herein shownand described is one embodiment thereof, it is-manifest that'the same is-sus- Patented Dec. 1'7, 1912.

ceptible of different embodiments, and being capable of changes in the form, proportion andminor details of construction, the right is reserved to modify or vary the invention as falls Within the spirit and scope thereof.

In the drawings, Figure 1 is a side elevation of a singeing machine constructed in accordance with the present invention. Fig.

'2 isa similar view taken at'right angles to the point of view in Fig. 1.- Fig. 3 is a top plan, view of the machine illustrated in Figs.

' 1 and 2. 'Fig. 4 is aplan view illustrating another" form of carrier for the stockings.

Referring in detail to' the drawings, the 3 numeral 1 designates-the main frame of-the jramebe'i'ng' of suitable conmachine, said struction and material, and mounted within said frame is a vertically-extending shaft 2, the lower'end of said shaft being arranged in a suitable bearing 3 formed m a transversely-extending support 4 adjacent the lower end of said frame. At the top of the shaft 2, and'at a point above the upper portion of the frame 1, is a head 5, said head being fixedly connected to the. shaft 2 through the medium of a binding nut 6, and thus'rotatable'with the'shaft 2. The head 5 constitutes a rotatable carrier, and supported by the latter is a series of radiallyextending forms 7 designed to carry the stockings during the steps incident tosingeing. These forms 7 are preferably constructed in skeleton outline, to which end the same may be made of heavy wire, and by reason of such construction it is apparent that the stockings will be effectually distended when upon the forms, and while dishold the stockings tended the stockings are capable of admit? tin the hot gases of the singeing flames to an through the interstices o the stockin s. Moreover, the wire forms 7 will permit t e hot gases to penetrate from both sides of the stockings without, however, burning thesame, so that the singeing is effected to the "required extent in a most thorough manner.

Each of the forms 7 slightly tapers from its outer end to the inner endthereof, and hence this taperin of the forms acts to mly in place when the same have been applied to the forms.

Arranged in diagonal relation to the head 1 5 is a pair. of burner tubes '8. These tubes are arranged also in parallel relation to each other, and are spaced a suflicient distance apart to permit. the forms 7, charges with the unsinged stockings,.to readily pass therebetween, and the lower sideof the upper tube, and the upper sidev of the lower tube are perforated for the exit of the gases that constitute the singeing flames. The

tubes 8 are supported through the medium of a feed pipe 9, which feed pipe may be held in position in; any suitable manner, and it will be understood that suitable mixing devices are employed with thefeed pipe 9 to produce the necessary admixture 0 air and gas for the singeing flames.- Also arranged in diagonal relation to the head 5 is a pair of rotary brushes 10,' these brushes being ournaled in a suitable supporting frame 11, and said frame is provided with upper and lower horizontally-disposed legs 12 in each of which oneof the brusheslO is journaled. The brushes 10 are in suflicient proximity to each other that when the forms '7, charged wit-h the stockings, leave the burner tubes 8, the same will pass between the brushes l0 and be acted on by the latter to brush off the carbonized fiber produced by the singeing flames, it being understood that rotary movement is given to the brushes 10 to effect such brushin action during the passage of the fOIIIlS. 0 this end each of the brushes 10 is provided with a suitable gear'13, mounted upon the outer end of the brush axis, said gears meshing with each other, and, thereby imparting reverse movement to the brushes, and for driving the latter a pulley 14 is mounted upon the axis of one of the brushes to which power is applied in the manner hereinafter to be descrlbed.

As before premised, the present invention has in View the production of a machine' wherein provision is made for automatically feeding the stockings to and stripping the same from the forms. For effecting the feeding of the stockings a pair of brush conveyers 15 is employed. These conveyers are preferably of a length equivalent to the length of an ordinary stocking, and are each supported by a pair of pulleys 16 carried by shafts 17, said shafts being journaled 1n parallel arms 18 of a supporting frame 19. The arms 18 are spaced sufliciently apart to permit the forms 7 readilyto pass therebetween, and by reference to Fig. 3, itwill be observed that the brush conveyers; 15 are arranged in such relation to the main frame 1 as to normally cover substantially the entire length'of one of the forms 7. The outermost shaft 17 of. each of the conveyers 15 is provided with a gear 20, said gears intermeshing in order to drive the contiguous stretches of the conveyers in the same direction, or toward the head 5, and one of said shafts 17 is provided with a driving pulley 21 throu h the medium of which power is applied for the operation of said brush con veyers. Manifestly, the bristles of the conveyers 15, at'the contiguous stretches thereof, will be in-such close proximity as to con- I tact with the form 7 between the conveyers,

so that when a stockin is introduced between the outermost ends the bristles will act to force the open end of the stocking upon the form and feed the stocking along the latter. In this feeding it is also apparent that the stocking will be brushed along the form, and all wrinkles therein entirely eliminated, so that when the form leaves t thereon is ready for presentation to the action of the singeing flames.

For stripping the singed and brushed stockings from the forms 7 i apair of rotary brushes 22 is positioned in diametrical relation to the frame 1, and'at a point to act upon the singed stockings after the same have left the brushes 10. These brushes 22 are journaled in a suitable supporting frame 23, and the axis of each of saidbrushes is provided witha driving pulley 24. 'These pulleys, however, are not in vertical alinement, and are each driven by a separate belt from a pulley 25 carried by a shaft 26, which e conveyers 15 the stocking of the conveyers latter is journaled in the frame 23 and provided with tight and loose pulleys 27 and 28.

Obviously, the brushes 22 must rotate in opposite directions, and to effect this end a straightlbelt 29 connects the pulley 25 with the "pulley 25. ThG'POSltlOD of the brushes 22in relation to the forms'fl, is such that when the outer end ofeach of th'e'latter is projected between said brushes a suflicient portion of the stocking is introduced to the bight of the brushes to enable the latter to draw the singed stocking from the form, and in passing from the brushes 22 the stocking may be deposited either in a suitable receptacle forthe same, or into any de sired form of conveyor for taking the stocking from the machine. 7

In the operation of the forms 7 to and through the machine it is requisite that a dwell of predetermined length should be given to the formsto permit the feeding ofthe stocking to each form and stripping of the same therefrom after being singed. That this may be done the shaft 2 is provided with a mutilated miter gear 29 with which a second mutilated miter gear 30 meshes. It is to be observed, however, that the gear 30 has only a segment provided with teeth,

and the arrangement of the mutilated portions of the gears 29 and 30' is such that-theformer makes only one-quarter of a revolution to one revolution. of the latter. Therefore, an intermittent drive is provided for the shaft 2, and the throw of the latter, under the influence of such drive, is only suflicient to carry each form 7 one-quarter ofthe circumferential path about the shaft 2.

"The gear-30' is carried-by. a shaft 31, suit-- ably journaled in the frame 1, and mounted upon said shaft is a gear 32 that meshes with a pinion 33 carried by a jack-shaft 34,

said shaft'34 being provided with tight and loose pulleys 35 and 36, respectively, through the medium of which power is applied to the shaft 34.

A line shaft 35 is employed for driving the respective mechanisms previously described, and that-the power may betrans mit-tcd from this shaft to. said mechanisms a belt 36 that traverses idler pulleys 37 con-- neets the pulleys 35 and 36 with a pulley 38 upon said shaft 35; a'belt 39 likewise passes over idler pulleys 40 and connects the pulley 14 with a pulley 41 upon the shaft 35; a belt 42 connects the pulleys 27 and 28 with a pulley 43 alsomounted upon said shaft 35, and a belt 44, which passes over idler pulleys 45, connects the pulley 21 with a pulley 46 carried by the shaft 35. .Through' the; medium of these belts it will be seen that so long as the shaft 35 is continuously operating, continuous operation will be imparted to the brushes 10 and the brushes22;

likewise to the brush conveyers 15, but the operation of the shaft'2 is dependent upon 'the positioning of the belt 36 upon the tight and then by the brushes 22't0 strip the stockings from the forms. s p

In the operation of the hereindescribed machine the mouth of a stocking is intro= duced between the outermost ends of the brush :conveyers 15. The contiguous stretches of these conveyers, moving toward 4 the head'5, it is obvious that the stocking will be brushed alongthe form that is be tween .said conveyers. During this move ment it will be understoodthat the shaft 2 is at rest; The inovin of the shaft, however, is timed so that after the stocking has been po'sitioned'upon the form between the conveyers 15 said shaft will be operated by the gears 29 and 30-fo'r'moving the stock ing and its form approximately degrees about the circumference of a circle thecentr of which is the shaft 2. .This positions a second form between the brush conveyers l5, and on the next movement of the shaft '2 the first stocking is carried between the burner tubes 8, at which point it is subjected to the singeing action of the flames of said tubes. In thls movement, however, the stocking does not dwell between the burner tubes, but its transit therethrough is only sufficient to enable the loose fibers to be earbonized, and the next dwell of the shaft 2 positions. the first stocking between the burner tubes 8 and the brushes 10. When the shaft- 2 is again moved the first stockin i iscarried between said brushes 10, at whic point the carbonized fibers are removed from the stocking, and when the shaft 2 again comes to rest the first stocking is positioned with its toe portion between the brushes '22. These brushes being in operation, the stock-.110 ingis caught in the bight thereof and removed from the form upon which it was originally placed, and on the next movement of the shaft 2 the form from which-W the stocking has been thus stripped is presented 1 15 to the brush conveyers 15, at which point an unsingedstocking is passed'thereon'. This cycle of operations is repeated durin the operation of the machine, and it wi l, of course, be'understood that the speed of the 12 shaft 2 is proportioned in accordance with the speed of the feeding and stripping mechanisms so that theshaft 2 will not be disproportionate to the feeding and stripping of the stockings, nor-such as to interfere either with the proper-application of the' stocking to the form, or the stripping ofthe singed stocking from the form upon which it has been carried.- It will'be' further an derstood that if so desired the stockings my der such conditions, the number of forms 7 carried by said carrier is limited in a measure, and consequently the number of stockings to be fed to the carrier will be limited by the number of forms thereof. To increase the capacity of the carrier, it is ob- 'vious that the number of forms 7 may be also increased, and to meet these conditions the structure illustrated in Fig. 4 is employed; Referring to that figure it will be observed that the forms 7 are mounted upon an endless conveyer 47, which conveyer may be in the nature of a sprocket chain, or made up of links, and the conveyer 47 is carried by a pair of rotating heads 48 the axis of one of which may be the shaft 2, and driven thereby in the manner described for the form of carrier illustrated in Figs. 1, 2 and 3; The driving of the conveyer 47 may be such as to cause .only one of the forms 7 to pass through the successive mechanisms at each movement of the shaft 2, but-if it is desired to increase the speed of the machine this driving may be so proportioned that the periodical movement of the conveyer will be such that two, three, or more of the forms 7 will pass, through the respective mechanisms, in which event it is very obvious that -the application of the unsinged stockings to the forms must be in such numbers at a single-time as to correspond with the number of the forms caused to pass at one time through the various mechanisms. This proportion may be readily determined by the mechanic, and obviously requires no further description.

A convenient construction for the head 5 is to form the same of sections, the latter serving to clamp the forms 7 therebetween, but 1t is obvious that the head may be solid, and the forms 7 secured thereto in any desired manner as will readily suggest itself to a skilled mechanic.
